While I am very content with the handling of my 3100 with suspension upgrades that include front and rear Helwig sway bars, Bilstiens, and a Steer Safe I thought why not go the whole way so I orderd a Blue Ox Tiger Trac bar. I consider myself fairly "handy" and have installed all the above mentioned myself with no problems at all. I read the Tiger Trac instructions several times and laid everything out before starting the job. I was 1 hour in to the process and all was going fine until I went to install the large frame bracket that mounts on the drivers side. I just could not get that bracket to where it needed to go, there are three wiring harnesses that are dead in the way and there is no slack what so ever to move them else where, there are fuel lines and there is some ABS "stuff" that is all so in the way. After a fair amount of time I just gave up and removed everything i had installed up to that point. I just can not see how that large bracket will fit into that small area withour significant risk of damging over time the wiring harnesses that feed the entire rear of the coach. has anyone else run into this problem on a 2012 E-450. In conclusion, I do not see this particular installation at a DIY project, the space tolerances are just way to tight in my mind. Thanks
